As for the HiDPI stuff, it's one example among many of Apple making sure basic functions work without friction. I don't even know what I traded off for that - my Macbook works with normal PPI screens just fine - but it was worth it. For another example, I recently had trouble pairing a bluetooth keyboard on Windows 11 because their new settings panel is missing functionality. In 2023, that is an absolutely wild issue to have.
Apple also removed sub-pixel rendering in 10.14 so on non-HiDPI displays text looks particularly bad compared to Windows or Linux. They also for some mind boggling reason don't support volume control over HDMI/DP with most monitors which is infuriating.
And the fact you need to spend $2000+ to get a laptop from them that can handle 2+ external monitors is NUTS.
What issue did you have pairing a Bluetooth keyboard in Windows 11? I've done that and had no issues even with ones that want me to enter a pairing code.
